Those of ordinary skill in the art, it can be understood that the above terms specific meaning in the present invention by the specific circumstances.

Referring to the drawings and will be described in detail with an embodiment of the present invention.

FIG. 1˜8 shown, a push-type caps, including external propulsion cover 1, inside the top of the cover 2, the striker 3 and 5 the impermeable cover, the inside of the top cover 2, striker 3 and spacer striker water cover 5 are located in the outer cover to promote internal I.

The inside of the top cover 2 is closely attached to the impermeable cover. The upper part 5 is formed with a hollow chamber inside the top of the top of the cover 2 is close to the inner wall of the external propulsion cover I, the interior roof to cover the upper part 2 with a telescopic device 22.

The impermeable cover layer 5 contains a pre-split impermeable layer 52, drain cover and the outer wall of the outer cover 5 between I advance is engaged, drain cover 5 by a threaded connection with the bottle is screwed.

3 is a plug as the striker inside the roof to cover the upper part 2 within the cavity and is located in the interior, surrounded by telescopic device 22 around the striker 3, section 3 of the striker tip 33 points to 52 but does not contact the impermeable layer, it may be provided in the interior cavity 4 effervescent tablets, powder and so on.

The cap 2 comprises an inner top lid 23, the plug portion 21 and the telescopic device 22, 21 and the insertion portion 22 are located in the telescopic device an upper lid 23, the plug 21 is provided in the middle portion, stretching means connected to the plug 22 and the portion 21 between the lid 23, the striker 3 in the socket plug 21. In other words the top of wall 31 of the striker fits in the cavity of the plug 21, as depicted in FIG. 1

23 is the lid and the bottom of the cover impermeable cover 5 above the external structure through a matched concave and convex structures 24, 51. A seal is formed in order to use effervescent pieces 4 with the outside air, the liquid inside the absolute isolation. The projection 51 of the vertical structure of trapezoidal cross section engages with the bit card 24.

The striker 3 is a rectangular-shaped arrow, including forming one phase at the needle shank 31 and a tip portion 33, the tip portion 33 and the needle shank 31 of the card 32. The card 32 is wider than the needle shaft 31. 31 provides on the pin shank at the card table in the middle card table 32. Card 32 is for engaging effervescent piece 4. 3 is the docked striker before the plug portion 21, the hollow effervescent 4 sets of striker 3 to the upper end of the striker. Quadrangular using arrow-shaped striker 3 can save raw materials.

The external propulsion cover 1 includes an outer portion 13 connected to each other and the inner lid part 11, the height of the cover portion 13 is larger than the inner lid part 11, the lower end of the inner lid portion 11 is provided with five claw clamp 12. Impermeable cover and the outer wall 5 of the card phase provide an engagement connection between the outer cover portion 13 and the inner lid part 11. Rib 6 prevents couples between 11 and 13 providing an extrusion.

The card includes a first position and a second 54-bit card card bit 55, the initial state jaw clamp 12 and the first 54-bit card is engaged, pressing or tapping the card to the second position 55 downward, claw clamp 12 and the second card bit 55 engages a non-resilient. 12 engages with 54.

Inner sidewall 111 and impermeable cover between the outer wall 5 by a respective uniform vertical projection 53 engages the inner cover portion. Enabling rotation of the external propulsion can be vertically raised lid I torque 53 between the cap and the bottle so that the whole effect of the separation.

The outer cover portion 13 below the impermeable cover and below 5 are connected with anti-theft ring 7 that is pressed down or tapping external propulsion. When I cover the claw-type clamps 12 to the second 55-bit card, external advance I travel cover, travel cover and the plug portion 21 of the security ring 13 of the same width 7.

The following describes the use of the device of the present invention:

1, I tear external propulsion cover theft ring 7;

2, by tapping an external force to promote the lid I thus promote the internal roof to cover 22 and the striker 2 telescopic device 3 linear thrust motion, when the external I cover advance of five claw clamp 12 cards in a second impermeable cover 5 55-bit card, the striker 3 is driven by the telescopic device 22 is cut in half strike impermeable cover 5 impermeable layer 52;

3, water 3 by being stretched striker impermeable layer 52 into the effervescent chamber 4 which, in turn carries an effervescent reaction;

4, hard cover portion 13 is rotated counterclockwise, by the inner lid portion and the inner wall 111 impermeable cover outer wall cooperating vertical projection 5 53-bit card, turn on all covers;

5, drain cover 5 comes with anti-theft ring 7 is left in the bottle mouth.

Thus, FIG. 1 shows a first relative position between the propulsion cover 1 and the impermeable cover 5. When the cover 5 is activated this causes the interior roof 2 to move downwardly engaging and thrusting the striker 3 to pierce the impermeable layer 52. With layer 52 cut through, then this allows the effervescent tablets to be released into the liquid that is therebelow. This action also now provides an engagement of the cover 1 with a different location of the cover 5 by means of the claw clip 12 engaging the ledge 55 rather than the ledge 54.

FIG. 1 illustrates the bottle cap arrangement in what may be considered a rest position, in which the theft ring 7 is still attached at the bottom of the propulsion cover 1. Once the theft ring 7 is removed, then the cap arrangement may be screwed further into the cover 5. In this regard, threads appear at 64. The top threaded portion of the bottle engages with the threads at 64. When the cap member is fully threaded, a bottom edge of the cover 5 sits against an annular ring that is below the threaded section of the bottle. The annular ring (not shown) limits how far the cap can be threaded onto the bottle. When the cap arrangement is fully threaded, then the bottom lower edge of the cover 5 can no longer be threaded.

Once in this position, the top surface 62 of the propulsion cover 1 can be tapped against a flat horizontal surface for the purpose of injecting the effervescent pieces 4 into the water content within the bottle. This occurs by means of the following action. The tapping at surface 62 causes the cap 2 to deflect at the telescoping or pleated accordion surface 52. This action where the cover 1 engages the plug 21 of the cap 2 causes the striker 3 to break through the layer 52. This action then enables the effervescent pieces, or portions thereof, to be ejected into the water or other liquid within the bottle.

This action, at the same time, causes the claw clips 12 to disengage from the ledge 54 and instead engage with the ledge 55 of the cover 5. The clips 12 ride over the surface 59. The propulsion cover 1 is thus now in a new position relative to the cover 5.

The foregoing is only preferred embodiments of the present invention, it is not intended to limit the present invention, any modifications within the spirit and principles of the present invention, made, equivalent replacement, or improvement should be included in the within the scope of the present invention.

The above descriptions only relate to the preferred embodiments of this invention, and do not restrict this invention. All the modifications, equivalent substitutions and improvements made based on spirit and principle of this invention are included in the protective range of this invention.
